Chennai summer resumes, Nungambakkam records 38.6

After a brief reprieve, Chennai’s summer has resumed. Yesterdays max temp was 38.6c. The same can be expected today also with a slight chance of evening Thunderstorms. Meanwhile Chennai’s long wait for a strong TS continues.

Good morning friends! One thing seems to be clear.. Swm along with the require moisture surge has not yet reached chennai! Still the limit is just under chennai latitude is what I feel.. Let’s hope it pushes further up and paves the way for our first TS soon..

Without knowing the cross section of our weather-cycles (Hadley-tropical, Ferrell-sub-tropical and polar cycle), we can never be “masters” in weather-dynamics. Please view 3D-cross section of our tropical Hadley cycle.

So mostly during seasonal rains, our weather will be confined to our Hadley-cycles. any changes in weather-dynamics within our Hadley cycles are interlinked within short-time lags.

Please don’t think that our earth (Hadley cycle) is so big, then there will be lot of time-lags. Please don’t forget that earth (Hadley cycle) is too big for us, but not for earth (Hadley cycle) itself 🙂

The unstoppable rally in increase in SOI continuing. If this increase in SOI continues then SOI will soon touch “0” or even become +ve in no time. Can it become +ve to surprise Elnino-forecasting agencies? Need to see 🙂

As I am proceeding to Bangalore (company forced me to go there for 2 days, my peer is on leave 😦 ) by 6 AM KSRTC Volvo, I can see gray skies and hint of a drizzle. I wonder how the Bangalore climate is today..Will update again from Anandam restaurant beyond Vellore..

A tiny raindrop is a droplet. Any raindrop > 1/2 cm splits into several droplets by the time it hits the ground. Sleet (frozen rain, in TN we get sleet only in Ooty (Mukurthi) and Kodai upper reaches) can fall in several sizes though.

Large raindrops mean that there are strong updrafts inside the clouds
above your head. These upward blowing winds can hold raindrops inside
the clouds for a longer period, allowing them to continue to grow in
size until they finally become heavy enough for gravity to finally win
the battle over the updraft, allowing the raindrop to fall to the
ground.
That’s why thunderstorms tend to have large raindrops, as they tend to
also have strong updrafts.

CPC s latest outlook of Tropical hazards has stated in its report of a possible Kelvin wave related activity to have contributed to Cyclone Ashobaa s formation over the Arabian Sea ………..

“The RMM-based and CPC velocity potential MJO indices indicate a strengthening signal since the beginning of June. The 200-hPa Velocity Potential anomalies are currently consistent with a coherent MJO, and an eastward propagation is observed during the past week. Other modes of tropical convective anomalies are apparent in the OLR field, including an atmospheric Kelvin Wave that likely contributed to the development of a tropical cyclone in the Arabian Sea.”

On no…!!! CPC should not have made this mistake….mentions Cyclone Ashobaa to move towards Somalia in their written statement , and expects above average rains on its track, but the map shows correct area – Oman coast ..Lol…they could have gone for a proof reading once before letting this out….

An IMD official told TOI on Wednesday, “The monsoon current will strengthen again when the cyclone weakens in another 48 hours. The monsoon will then progress northward. Monsoon rainfall for June is already going to be less than normal in many parts of the country. And Ashobaa may cause a further rainfall deficiency this month.”

Another senior IMD official said the cyclone basically began moving towards Oman, taking away all the monsoon moisture with it. “Conversely, had the cyclone re-curved and hit Gujarat, the monsoon would have begun advancing over the rest of the country. That, however, did not happen,” the official said. This ultimately resulted in the monsoon being drawn out of the country, except for the southern parts of India, officials said.

Heat wave in India? It will only get worse in years to come: Study
“From climate model projections, we have pointed out that there is a possibility of high occurrences of heat waves in South India in future,” Subimal Ghosh, associate professor at the Department of Civil Engineering, IIT-B, and one of the paper’s authors, told IndiaSpend.

Under the most probable-case and the worst-case scenarios, 2070 onward, there could be an increase in intensity, duration and frequency of severe heat waves.
In particular, a large part of southern India, east and west coasts, which have been unaffected by heat waves, are projected to be severely affected after 2070.

closed stadiums will mitigate the effect of dew, and other weather parameters in the air, and the game will suffer, of course there is a stadium like this in Australia it rarely used for competitive cricket

East West Shear to form on June 17th and either side there will be UAC
and Both sides they descend to sea level as LPA. Chennai falls under its
influence. Great days ahead.
i need this as featured comment please

why chennai lacking rain even delta region , through out tamilnadu receive decent rain only chennai not receiving rain please explain ,in south west monsoon normally chennai receive good rain these year still not receive any good rain why what is the reason please explain?

Got off at some junction under a bridge in Bangalore. Driver told me to take another local Volvo to ITPL Blr. Apparently, local Volvos charge close to Rs 100 in B’lore for around 20 kms. V pleasant weather, breezy and clouds interspersed with sunshine. Wish Chennai had such weather, minus B’lore’s mad traffic.

1.40pm Finally, the inevitable. Play has been called off for the day. Join us tomorrow morning at 9.30 local time for (hopefully) the start of day three, with India resuming at 239 for 0. Until then, ta ta!
